This would be fun, as long as people have the same ingame content (game version), you guys might want to add what version of the game you have since there is 3 different versions of the game out in stores, and 2 of the games have extra maps.
Standard Edition: None of the ones written under, just the regular maps
Signature Edition: 1 Extra map - Moscow Suburbs
Digital Deluxe Edition (Steam): Drilling Ship & Moscow Suburbs
Make sure to skip these levels unless the maps are ingame, just not unlocked, hence the host must have to have the map for everyone else to play them, but I really doubt that is the case.
